my dad did this calculation when looking at new cars a 12k yaris vs a 24k hybrid.. Yaris won even with its 10mopg less fuel rating.. and he calculated 15 year ownership.. however he cant predict the price of gas in there accurately, so he went with a even $4 a gallon..
The one huge draw back of hybrids are the batteries , if these go bad out of warrantee your in for a big expense.. however hopefully in that warranted time they will decrease in cost and increase in capacity making old hybrids more of a plug in hybrid.. only time will tell.. However if batteries get better we may see these hybrids getting more plug in conversions in the future or better MPG ratings with new batteries and computer reprograms.
Time will tell, do what you can now..
